Defects Analysis
Defects are failures in function, performance, compliance, or usability that appear in a building’s structure, fabric, services, or facilities. KEYS Consulting brings deep expertise in identifying these issues and specifying effective, tailored remedial solutions.
Pinpointing Building Faults
Effective building assessment requires a deep understanding of construction methods, usage patterns, alterations, and maintenance history. By diagnosing current defects and anticipating future issues, we provide a comprehensive view of a building’s condition.
Defects may be revealed through occupant complaints or discovered during professional inspections. For property portfolio holders, we strongly recommend regular surveys to reduce the risk of costly remedial works.
Scientific Defects Decoded
When faced with complex defects or conflicting information, a scientific, evidence-led approach is essential. We test hypotheses against known or observed conditions to deliver clear, accurate conclusions. Our methodology follows a structured, staged process designed for precision and reliability:
- Observations – Record visible symptoms
- Theories – Develop hypotheses based on findings
- Questions – Identify key factors to differentiate theories
- Tests – Conduct specialized surveys or testing
- Analysis – Interpret results and refine diagnosis
- Conclusions – Match findings to symptoms
- Feedback – Adjust questions to incorporate new data
- Action – Plan effective remedial works
Common Building Defects & Their Causes
Defective Concrete, Spalling, or Loose Plaster in Ceilings
Symptoms:
- Water/rust staining, water leakage
- Patterned cracking
- Bulging, loose concrete patches with exposed rusty reinforcement
Possible Causes: Aging concrete is a common issue in old buildings. Persistent water leakage weakens the steel reinforcement, leading to structural degradation.
Water Seepage from External Walls, Windows, Roof, or Ceiling
Symptoms:
- Water staining
- Peeling paint or wallpaper
- Water dripping
- Fungus growth
- Defective concrete, plaster, or tiles
Possible Causes: Seepage can result from cracks in external walls, defective window sealants, or faulty drainage pipes. These issues need prompt attention to prevent long-term damage.
Structural Cracks in Walls
Symptoms:
- Deep cracks through finishes into concrete or bricks
- Long, continuous cracks across the wall
- Diagonal cracks at window or door corners
Possible Causes: Cracks can be caused by structural movement, ground settlement, overloading, or poor construction design. A detailed investigation is required to determine the exact cause.
The Real Price of Defects: Are Remedial Works Cost
Remedial costs depend on factors such as the type and severity of the defect, accessibility of the work, material and workmanship standards, project planning, and compliance with client and regulatory requirements.
At KEYS Consulting, we align our recommendations with the client’s maintenance strategy and budget, tailoring remedial solutions to suit the specific nature of the defect.
